13. Modulatory effect of baicalein on gene expression and activity of antioxidant enzymes in streptozotocin-nicotinamide induced diabetic rats
Oxidative stress plays the central role in the pathogenesis and progression of diabetic complications. The present study aims to investigate the beneficial effect of oral administration of flavone baicalein in streptozotocin-nicotinamide (STZ-NA) induced diabetic rats by measuring oxidative stress markers, antioxidant enzyme activities and expression analysi

15. Effects of different sources of selenium supplementation on antioxidant indices, biochemical parameters, thyroid hormones and Se status in transition cows
ABSTRACT. The aim of this study was to determine the effects of supplementing close-up and fresh dairy cows’ diets with sodium selenite or organic sources of selenium (Se) on the serum biochemical parameters and antioxidant indicators and Se status. Twenty-four multiparous Holstein dairy cows were balanced by body condition score (BCS), previous lactation

16. Supplementation of Natural Antioxidants to Reduced Crude Protein Diets for Japanese Quails Exposed to Heat Stress
ABSTRACT The study aimed at comparing the effects of the supplementation of natural antioxidant sources to a reduced crude protein diet on the performance, carcass traits, blood parameters, liver antioxidant enzyme activities and meat lipid peroxidation of Japanese quails exposed to heat stress. A total of 640 14-day-old male Japanese quails were exposed to

17. Health benefits of subcutaneous zinc edetate and diphenyl diselenide in calves during the weaning period
Abstract: The aims of this study were to investigate whether treatments with zinc edetate (Zn) and diphenyl diselenide ((PhSe)2) enhance performance, immune responses, protein metabolism, and oxidant/antioxidant status in calf serum and muscle. Animals were divided into four groups (n=6 each): control (without supplementation), and groups supplemented on day

18. Stability of antioxidant vitamins in commercial vitamin supplements
The stability of vitamins A, E, and C was determined in 12 brands of vitamin supplements over a 12-month storage period. The variations in concentrations of these vitamins across three different batches of five brands were measured. Vitamins A and E was determined by HPLC method, and vitamin C was measured by using potentiometric titration. All samples for s

19. The pequi pulp oil (Caryocar brasiliense Camb.) provides protection against aging-related anemia, inflammation and oxidative stress in Swiss mice, especially in females
Abstract Continued exposure to reactive oxygen species and inflammation are the rationale behind aging theories and associated diseases. Scientific evidence corroborates the ethnomedicinal use of the oil of pequi (Caryocar brasiliense Camb.), a typical Brazilian Cerrado fruit, against oxidative damage to biomolecules and inflammation. We aimed to investigate

20. Fatty Acid Composition and Carotenoids in Raw and Grilled Tilapia GIFT Fillets Supplemented with Lycopene, β-Carotene and Lutein
This study evaluated the incorporation of β-carotene, lutein and lycopene into tilapia (genetically improved farmed tilapia, GIFT) fillets supplemented through 0, 20 and 40 days, and their influence on the fatty acid composition and nutritional quality of raw and grilled fillets. A control diet and a diet containing those carotenoids were elaborated with th

21. Extraction of β-glucan of Hericium erinaceus, Avena sativa L., and Saccharomyces cerevisiae and in vivo evaluation of their immunomodulatory effects
Abstract Beta-glucan (BG) is one of the most common types of polysaccharides, and is a potent immune activator. It is present in microbes, plants, and mushrooms. The immunomodulatory properties of BG are varied among different species. This paper explains the composition of BG from yeast (Saccharomyces cerevisiae HII31), oat (Avena sativa L.) and mushroom (

22. Antidiabetic, antihyperlipidemic and antioxidant influences of the spice cinnamon ( Cinnamomum zeylanicumon ) in experimental rats
ABSTRACT The present study investigates the effect of cinnamon (Cinnamomum zeylanicumon) powder supplementation on glucose levels, lipid profiles, and oxidative stress parameters in alloxan-induced diabetic rats. Diabetes was induced in adult male Wistar rats via a single subcutaneous alloxan injection (15 mg/kg). Cinnamon powder was mixed with the standard

24. Protective effects of silymarin on methotrexate-induced damages in rat testes
Abstract The present study aimed to investigate the protective effects of silymarin (SMN), an antioxidant, on methotrexate (MTX)-induced damage in rat testes. Thirty-two Wistar albino rats were divided into four groups (n = 8): control, MTX (20 mg/kg, i.p. on days 1 and 5), SMN (200 mg/kg, orally), and MTX + SMN (20 mg/kg, i.p. on days 1 and 5 and SMN 200 mg
